The decision to upgrade the Subaru WRX STi slowly has been something of a mistake for Subaru and they are now looking at being left behind.
When the Subaru WRX STi first came onto the market it offered a 300 horse power engine and during the time it has been out it has received just a few upgrades. At the moment it offers up 305 horses and this is just 5 horses more than some years ago.
This isn’t a bad number but bear in mind that it is less that what some of the competitors are offering in their vehicles. At the moment the biggest rival is the Ford RS and this offers up an engine with 350 horses.
At the moment Subaru is working on the next version of the Subaru WRX STi and when it arrives in 2018 fans are hoping that it is going to arrive with a 2 litre turbocharged engine that offers up 232 horses.
